Diagnosis. Differs from C. diehappy   as follows: Palpal RVTA with stalk of moderate length; RDTA a thick, distally hooked process; MA processes small, subequal in size. Epigynal septum widened at middle; paired fossae with short lateral extensions.


Male (holotype). BL 5.93, CL 2.95 (range 2.78–3.47), CW 2.22, CapW 1.09, EGW 0.83, LL 0.40, LW 0.40, SL 1.45, SW 1.24. Legs: 1423 (I: 11.82; II: 9.42; III: 8.40; IV: 10.98); ratio tibia I length:CW = 1:0.73. Male palp ( Fig. 6a,b View Fig ). RVTA stalk longer than in C. diehappy   ; RDTA thick, curved and hook-like distally. Distal loop of sperm duct U-shaped with parallel limbs. Embolus a basally wide, curved rod with a subapical barb ( Fig. 2b View Fig ). MA processes subequal, lateral process usually membraneous.

Female (KS74066). BL 6.40, CL 2.95 (range 2.24–3.47), CW 1.85, CapW 1.35, EGW 0.90, LL 0.41, LW 0.43, SL 1.41, SW 1.23. Legs: 1423 (I: 9.89; II: 8.13; III: 7.16; IV: 9.25); ratio tibia I length:CW = 1:0.73. Epigynum ( Fig. 6c,d View Fig ). Median septum widest at middle. Paired fossae with relatively short lateral extensions (cf. C. diehappy   ). Internal genitalia with very short copulatory ducts, about as wide as spermathecae.

Distribution. South-eastern New South Wales to the Border Ranges area of NSW and southeast Queensland.

Etymology. The specific name refers to Kioloa State Forest, a collection site.
